London rents reach a record high as supply shrinks and demand climbs

Current growth rates 'cannot be sustained,' says Savills, as its prime lettings index records the highest annual increase since it started in 1979.

"Rents in Inner London are on track to reach pre-pandemic levels by the middle of 2022," says Hamptons.

"The property markets in central and outer London are increasingly on different trajectories," says Knight Frank, as the latest market indices shine a light on sales and lettings trends.
